Hi:

I have a 93 (or 94?) trek 970 which has a worn out rear rim (concave, brake grabbing, etc).

I'd like to replace the wheel with a sealed bearing hub good quality wheel that allows for rim braking (wayyyy before disk brakes) and stay at 7 speed so I don't have to upgrade the shifters, etc.

I am a little confused in reading the posts on a couple of items

(1) if the wheel is a disk brake wheel (and I obviously skip installing the disk), is it still OK for rim braking (i.e. do they make rims different now?)

(2) Assuming it has a free hub (my current wheel has a freewheel), can I find a seven speed cassette, and will it fit OK, as most cassettes are 8+ speeds now.

If anybody could point me to the correct wheel to order I'd much appreciate it. I'm willing to pay a bit for this, because I hate cheap parts, but don't want to break the bank for this older bike.

Thanks!
